<h1 id="dovecot">开启 Dovecot 调试模式</h1>
<blockquote>
<p>不知道 Dovecot 的配置文件在哪个目录？请查阅这个教程：
<a href="file.locations.html#dovecot">iRedMail 主要组件的配置文件和日志文件路径</a>.</p>
</blockquote>
<p>要调试 Dovecot，请修改 <code>dovecot.conf</code> 的如下参数：</p>
<pre><code>mail_debug = yes
</code></pre>
<p>之后重启 Dovecot 服务。</p>
<p>如果需要查看验证和密码相关的调试信息，请修改如下参数并重启 Dovecot 服务：</p>
<pre><code>auth_verbose = yes
auth_debug = yes
auth_debug_passwords = yes
auth_verbose_passwords = yes
</code></pre>
<p>如果重启 Dovecot 服务时看到很多错误信息（例如：<code>dovecot fails, spawning too
quickly</code>），可能是由于 Dovecot 配置文件中有某种错误导致的。请在命令行手动重启
Dovecot 服务，它会报告配置文件的错误：</p>
<pre><code># dovecot -c /etc/dovecot/dovecot.conf
</code></pre><div class="footer">
